jQuery grid with multiselect

I'm looking for grid with multiselect, based on jQuery. Purpose is time frames selector, so user get grid with

 day1 |  day2 |  day3 
00:00 | 00:00 | 00:00  
00:30 | 00:30 | 00:30  
01:00 | 01:00 | 01:00  
01:30 | 01:30 | 01:30  
02:00 | 02:00 | 02:00  
03:30 | 02:30 | 02:30

etc. User should be able to select multiple time frames for multiple days 开发者_如何学编程(so I need selection for cells, not rows as in usual datagrids). Also Shift+mouse / Ctrl+mouse selection merging needed. Could anyone suggest existing module with such functionality?
